[Q] Sound is very low on Y duos S6102 with Hyperion 8 (port)

I tried to increase my device's overall sound by following this and this posts. In the first post, it is told that "*#*#3646633#*#*" is dialed to enter in engineering mode. In the 2nd post, it is said * # * # 197328640 #*#* brings menu consisting "service mode, sound, device" bla bla bla.

But my problem is none of these codes work with Hyperion 8 (port).

There are some audio tweaks built in only for music and video playing. Not for overall improvement.
